Do you feel your contributions in the workplace are overlooked? Are you consistently swamped with work at the office, but still feel empty when the week ends? At the end of the day, are you ashamed of what you've accomplished and how you reached the end result?

If you answered "yes" to any of these questions, it might be time to reassess your career and find something a bit more fulfilling. A career in nonprofits might be your answer.

Advocacy, grantmaking and civic organizations -- also known as nonprofits -- are groups that don't exist to make money, but to serve and promote the common good to better their communities. Nonprofits run the gamut from soup kitchens and homeless centers to hospitals and charitable associations. Many of such organizations depend on small staffs of paid employees and volunteers.

Nonprofit organizations employed 1.2 million workers in 2006 and rank in the top 20 fastest-growing fields, according to the Bureau of Labor Statistics. There were 837,027 charitable nonprofits in the US in 2003; a 68 percent increase since 1993, according to the most recent information from the National Council of Nonprofit Associations.
